摘要
沿空留巷技术是提高煤炭回采率、减少巷道掘进量、缓解采掘接替紧张的一种行之有效的方法。目前,沿空留巷技术已经在很多煤矿中得到应用,并取得了较好的经济效益。简要分析了沿空留巷技术的优势及应用沿空留巷技术的关键问题,并探讨了在深部岩层应用沿空留巷的可行性,为深部岩层沿空留巷的应用提供一定的参考。
The gob-side entry retaining technology is an effective method to improve the coal recovery rate,reduce the amount of roadway excavation,and relieve the tension of mining replacement.At present,the gob-side entry retaining technology has been applied in many coal mines,and has achieved good economic results.This paper briefly analyzes the advantages of gob-side entry retaining technology and the key problems of its application,and discusses the feasibility of application of gob-side entry retention technology in deep strata,so as to provide a certain reference for the application of gob-side entry retaining technology in deep strata.
